when a cannonball is fired, the equation of its pathway can be modeled by h=-16t squared + 128t. find the time it will take for
Rashid [163]
At the time the cannonball reaches the ground, the vertical height of the cannonball from the ground is 0, i.e. h = 0.

Thus, the time it will take the cannonball to reach the ground is given by

-16t^2+128t=0 \\  \\ \Rightarrow t(-16t+128)=0 \\  \\ \Rightarrow t=0\ or\ -16t+128=0 \\  \\ \Rightarrow16t=128 \\  \\ \Rightarrow t= \frac{128}{16} =8

Therefore, it will take the cannonball 8 seconds to reach the ground.

How many, and what type of solutions, does3x2−x−5=0 have?
siniylev [52]

Answer:

2 irrational solutions

Step-by-step explanation:

using the quadratic formula:

\frac{ -b \:± \sqrt{b {}^{2} - 4ac }   }{2a}

3x²−x−5=0

where a = 3, b = -1 and c = -5, plug in those values in the quadratic formula

\frac{ - ( - 1)±\sqrt{(1) {}^{2} - 4(3)( - 5) } }{2(3)}

you get two solutions:

\frac{1 +  \sqrt{61} }{6} \:  and \:  \frac{1 -  \sqrt{61} }{6}

both can be written as:

\frac{1± \sqrt{61} }{6}

They are irrational as they cannot be written in the form p/q where p and q are whole numbers (integers)

Does anyone know this?
Marrrta [24]

Answer:

f(-9) = 279

Step-by-step explanation:

f(x) = 4x^2 + 7x + 18

f(-9) = 4(-9)^2 +7(-9) + 18

       = 4(81) - 63 + 18

       = 324 - 63 + 18

       = 279
